The case 17 is positioned on the front side. In other words, the transfer pipe 43 is interposed in a space (h) formed by the sub-transmission case 15b, the rotating case 17, the transplant tool 18, and the seedling mounting table 16. By doing so, not only the configuration becomes very compact, but also the transfer pipe 43 can be disposed without being bent left and right, and the clogging of fertilizer can be reduced. In addition, the discharge port 72 of the fertilizer feeding device 42 and the funnel 74 connected to the discharge port 72 are located above the rotary case 17, and the transfer pipe 43 is straightly arranged without being bent left and right. The structure does not hinder the operation of the implanter 18.

For the transmission of the drive shaft 53, a ratchet mechanism 94 as a one-way rotation mechanism is attached to the shaft 53, and an operating lever 95 as a drive connecting mechanism thereof is mounted on the shaft 53 via the drive rod 96. Crank 9 provided so as to project and rotate at one side portion on the lower end side of transmission case 15b
7 and the lever 9 is rotated by the rotation of the crank 97.
5 is oscillated up and down so that the drive shaft 53 is transmitted and rotated in a fixed direction.

The crank 97 corresponds to the rotating case 17
When the spur gear 99 is attached to the rotary shaft 98 of the above, and the crank transmission frame 100 is attached in place of the lid attached when the fertilizer application device 39 is not attached to the rear end of the sub transmission case 15b, the transmission frame 100 is previously provided with the crank transmission frame 100 inside.

The crank 97 is arranged at a slightly higher position in the rearward direction of the bearing metal (i) that encloses the rotating shaft 98 that largely projects laterally from the sub transmission case 15b. When the crank 97 is arranged at such a position, it is very effective because dirt and muddy water are less likely to be applied to the crank 97.

The fertilizer run-out sensor 103 provided in the fertilizer tank 41 is mounted on the lower slope of the tank 41 and is configured to receive fertilizer pressure for sensing. In order to position the fertilizer tank 41 as far forward as possible in a balance relationship, the wall surface of the tank inner surface is configured to have an inclination that the front side becomes gentle, and the sensor 103 is provided so as to be attached to this gentle inclined surface. Has been. In this way, even if the amount of fertilizer becomes small, the sensor can sufficiently receive the fertilizer pressure, and it is possible to accurately detect out of fertilizer. It goes without saying that the sensor 103 is connected to a buzzer or a warning light. Further, the air tank 4 is provided in front of the sensor 103.
Since the structure extends to the position where 7 is positioned, the sensor portion is sufficiently protected, and it is possible to prevent a situation in which a foreign substance accidentally collides with the sensor portion and is damaged or the detection performance is changed. 104 is a fertilizer clogging indicator,
The fertilizer is mounted between the rear surface of the rear plate 84 that is rotatably provided on the fertilizer application frame 40, and is suspended from the front surface of the inner wall of the grooving device 44 by a proper distance and the wall of the grooving device 44. This is displayed by detecting that electricity flows without difficulty between the two when it becomes clogged or when the fertilizer is in a state where the fertilizer is sufficiently dissolved in the muddy water that enters the grooving device.
According to the fertilizer clogging detection mechanism 106, accurate detection can be performed with little influence of mud or mud in paddy fields. Reference numeral 107 denotes an adjusting device for the detection mechanism 106, which adjusts the detection sensitivity according to the field. That is, by adjusting the electric conduction resistance, when the mud in the field at the time when the fertilizer has not been sprinkled yet has sufficient electric conductivity, the detection mechanism works to prevent false alarm.

Next, the operation of the above example will be described. First, when a large amount of spare seedlings are mounted on the side of the riding type traveling vehicle body 1, the spare seedling placement device 3 is used as shown in FIGS. 1 and 2.
1 is mounted on each of the front and rear brackets 29a and 29b to mount a large amount of seedlings. When it is not necessary to mount a large amount of seedlings, it is advisable to remove the preliminary seedling placement devices 31 on both front sides or both rear sides.

In this state, seedlings are mounted on the seedling mounting table 16 of the rice planting work machine 14, granular fertilizers are stored in the fertilizer tanks 41, and the transmission rotary parts are moved while the riding type traveling vehicle body 1 is moved forward. When driven, the seedling placing table 16 reciprocates left and right, and the seedlings are delivered to the lower end side thereof. Then, the transplanting tool 18 swings with the rotation of the rotating case 17, and the transplanting claws move in a vertically long closed loop-shaped transplantation locus, thereby dividing and holding one seedling per one plant from the seedling mounting table 16. Seedlings are planted on the soil surface of the paddy field leveled by the leveling floats 20 and 21.

On the other hand, each drive shaft 53 of the fertilizer application device 39 is driven by the crank 97 transmitted from the rotary shaft 98 of the rotary case 17 through the gears 99 and 101 so that the drive rod 96 and the lever 9 are connected.
5. Rotation is transmitted in a fixed direction via the ratchet mechanism 94. For this reason, when the clutch 54 is set to “ON”, the feeding roll 46 is rotated, the fertilizer is fed from the fertilizer tank 41 and discharged to the funnel 74 at the lower part, and flows down in the transfer pipe 43 to flow into the groove making device 44. It is discharged to the opening. At this time,
Compressed air from the blower 46 is accumulated in the air tank 47, and this high-pressure air is blown into the transfer pipe 43 below the funnel 74 via the wind conduit 48 and compulsorily flows down in the transfer pipe 43. Thus, the fertilizer sprinkled in the groove opened by the grooving device 44 in this manner is buried back below the soil surface with the soil cover plate 108 refilling the groove.

In this way, the seedling planting work and the fertilizing work are carried out at the same time. To adjust the feeding amount of each fertilizer feeding device 42, the gear 90 is moved to disengage from the gear 51. It is advisable to rotate the gear 51 in the forward or reverse direction to move the gear 51 left and right with the screw of the cylinder shaft 50, thereby moving and adjusting the payout adjusting roll 46b.
Further, in order to adjust the feeding amount of each fertilizer feeding device 42 at once, the rotation of the rotary shaft 89 with the lever 88 in the forward and reverse directions causes the gear 90 to rotate.
The gear 51 is rotated by and the adjustment can be performed in the same manner as described above.

Next, when the fertilizer in the fertilizer tank 41 is discharged after the work is completed, the fertilizer take-out trough 61 is opened as shown by the phantom line in FIG. When the member 66 is pulled out, the fertilizer in the tank 41 is received by the fertilizer take-out trough 61 and discharged as it is to the outside on the rear side. The fertilizer discharged should be received in a container as appropriate. Further, when cleaning the feeding roll 46 portion of the fertilizer feeding device 42 or other appropriate portions or draining water after cleaning, the blower 46 can be removed and air can be blown to easily clean and drain water.

Further, in particular, a fertilizer applying device 39 which applies a plurality of respective planting devices 19 to each of the seedlings planted in the field.
Since each fertilizer feeding device 42 of No. 1 is arranged in the machine left-right direction along the seedling mounting table 16 and attached to the machine as an integral structure with the fertilizer application frame 40, it is a riding type rice transplanter equipped with the fertilizer application device 39. The front-rear length of the machine can be shortened to obtain a small riding type rice transplanter with a fertilizer application.Because the front-rear length of the machine is short, it is easy to turn around the ridges during work in the field, thus improving work efficiency. Is also good. Further, since the fertilizer feeding devices 42 are arranged in the machine left-right direction along the seedling mounting table 16 and attached to the machine body as an integral structure with the fertilizer application frame 40, the attachment and detachment to and from the machine body are facilitated and maintenance workability is improved. Is also good.

Further, the air tanks 4 are provided on the front and rear sides of each of the fertilizer feeding devices 42 arranged in the lateral direction of the machine body.
7 is arranged, and the operating lever 95 and the driving rod 96 for driving the fertilizer feeding device 42 are provided on the other side.
5 and the air rod 4 without being disturbed by the drive rod 96
7 can be configured as a large-capacity air tank by extending it in the left-right direction of the airframe, and since it is increased in the left-right direction of the airframe to increase the capacity, the front-rear length of the airframe is the same. Although it is a riding-type rice transplanter with a short fertilizer application, stable compressed air can be sent into the transfer pipe 43, and proper fertilization work can be performed with less occurrence of clogging of fertilizer.
